Improvement in bull s-eyes



UNITED STATES PATENT CEEIoo WILLIAM W. WILCOX, OF MIDDLETOWN, CONNECTICUT.

IMPROVEMENT IN BULIIS-EVES.

Specification forming part of Letters Patent No1 162,445, daed April 20, 1875; application filed December 24, 1874.

To all whom it may concern:

Be it known that I, WILLIAM W. VVILooX, of Middletown, in the count-y of Middlesex and State of Connecticut, have invented a certain new and useful Improvement in Bulls- Eyes for Hoisting-Tackle, of which the following is a specication This invention is illustrated in the aecompanying drawing, in whichi Figure l represents a section in the plane a: a', Fig. 2. Fig. 2 is a section in the plane y y, Fig. l.

Similar letters indicate corresponding parts.

This invention consists in the combination of a metallic strap with a bulls-eye, said strap being made of a iiat strip of metal, one end of which is expanded to form an eye, while the two ends are united by a rivet, and applied to the wooden center having an annular groove, in such a manner that, by the said metallic strap, the bulls eye is protected against splitting, and at the same time the cost of the article is reduced.

In the drawing, the letter A designates a bulls-eye, which is made of wood, or any other suitable material soft enough to produce the least possible abrasion on the rope passing through it. This bulls eye is inclosed by a strap, B, which, in the example shown in the drawing, is made of a flat, half-round, round, or oval strip of metal, one end of which is expanded to form the eye C, the two ends being united by a rivet, a, as shown, said strap being fitted in a seat or annular groove formed upon the wooden center, so as to prevent lateral displacement, and, further, to prevent such center from splitting.

In bulls-eyes, as heretofore manufactured, straps of rope are used, and such straps are liable to stretch, and it' the bulls-eye is exposed to a heavy strain it is liable to split.

A bulls-eye provided with a metallic strap, according to my invention, is not liable to split, since the metallic strap, if properly applied, will encircle the same with a iirm grasp, and the body ot' the bulls-eye can only be split by .a strain hard enough to part the strap. Furthermore, I am enabled to apply my metallic straps to bulls-eyes at less cost than is required to apply the ordinary straps ot' rope, and consequently I am enabled to furnish an article of superior durability at reduced cost.

What I claim as new, and desire to secure by Letters Patent, is

The combination, in a bulls-eye, ot' a wooden body, A, having a central groove or seat, and a surrounding strap, B, constructed with an eye, C,substantially as herein shown and described, for the purpose specified.

. kWILLIAM WV. WILCOX.
